SeaWorld also looking into private sale?
Jan 6, 2013

We reported last week that SeaWorld Parks and Entertainment had filed for an initial public offering (IPO). However, some sources are now saying that the company is also looking into a sale with private equity firms instead of going public. SeaWorld and its sister parks are owned by the Blackstone Group.

The same sources say that the IPO is more likely, because stock in amusement parks has been selling well recently, so it would be a good time for SeaWorld to go public.

Included under the SeaWorld umbrella are 11 theme parks, including Busch Gardens and Sesame Place.
